Backup and Restore OS Setup

Backup and Restore is important part of development in Virtual Environments where for example new OS patch can for example block needed HW/OS features, so possibility of quick restore will save a lot of time

Format Backup Storage

I will as primary backup tool Linux, so I will format whole third disk as Linux partition.

Note: Checking if we have disk formated right, EXT3 file size have limitations , if EXT3 block size is only 1KB, max one file size can be 16GB, this can not enough for backups.

mke2fs -j -b 4096 -L backup /dev/sdc1

Initial OS backups with DD

We will backup initially all OSes with DD, because such all disk partitions sectors disk backup is OS FileSystem? and Backup tool format independent, is best for initial last resort restore backup solution.

For this project I will use a FS archiver, its have good support for various compression methods and it support then in multi-threaded form FS Archiver - compression, this is a good bonus on muli-core CPUs which we have in this new workstations.

Note: For OpenSolaris? I will use on File System level ZFS snapshots inside system.

Backuping OSes with FS archiver

I use a [ System Rescue Live-CD] which is build with latest FS archiver versions (Use version 1.3.x or newer).

Boot System Rescue CD in 64bit mode with aktker64 so you can use while 8+GB of RAM Memory (You need a lot of memory, if you want to use LZMZ compression)
